Thin Skin
The most superficial part of the epidermis is formed by the stratum corneum. Nuclei are not visible in this layer. Cell outlines may be visible at high magnification or, in the form of artefacts, as cracks or clefts in the stratum corneum. The stratum granulosum is formed by a single layer of very dark and flattened cells in thin skin. Several layers of cells containing keratohyalin granules are visible in thick skin. Polyhedral cells with clear outlines form the stratum spinosum. The stratum basale is formed by a single layer of cuboidal or columnar cells and delimits the epidermis from the dermis. The stratum basale sits on the basement membrane, a specialized extracellular matrix formed by contributions from the basal cells and the underlying dermis.
The dermis is the underlying skin connective tissue layer and not part of the epidermis.
